Agreed, I too think that both heavy metal and grunge convey an Odinic vibe. Metal in particular evokes a strong Germanic barbarian aesthetic, or at least what we modern people imagine that as being.

I think the wily old man might get a good chuckle out of the Alice in Chains song Them Bones. Heck, it could even be a devotional to Hel.
